Tags: Thunderstorm weather, how to protect UPS power supply The lightning protection of UPS power supply system and communication ports should be based on relevant national regulations, and according to the specific conditions of the application environment, and develop practical solutions based on local conditions, and establish effective , Scientific and economical lightning protection system. According to the characteristics of the UPS system, its lightning protection should focus on the following points: 1. It is necessary to improve the external lightning protection facilities and do a good job in the grounding of the computer room. According to the 'Electronic Computer Room Design SpecificationThe grounding should share a group of grounding devices, and the grounding resistance shall be determined according to the minimum requirements. If the grounding must be set separately, an equipotential grounding coupling must be installed between the two grounds. UPS protects large data systems and is more sensitive to lightning counterattacks. Even a small potential counterattack often causes unnecessary losses. 2. Choose lightning arresters. The market for this kind of products is relatively abundant. Try to choose a reputable and reliable lightning arrester. The grounding wire of the arrester should be no less than 6mm2, connected with the straightest and shortest lead. It is best to use Kay in the wiring method. The text wiring method minimizes the induced voltage on the lead. The lightning protection box for UPS power supply and the UPS power supply must be grounded, the lightning protection device and the UPS power supply must be equipotentially connected, and the UPS output line must have a ground wire. The grounding system is best to use high-quality grounding modules, which can ensure the reliability and corrosion resistance of the grounding resistance, and avoid the need to modify the grounding network every 1-2 years, which saves the user.
